Perhaps you should try some spelling variations:
"_ optimizedddr algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm"
"jose optimisation algorithm" » "jose optimization algorithms", "jose estimation algorithm", "jose estimation algorithms", "qoe optimization algorithm", "_ optimisation algorithm", "game optimization algorithm"
"_ optimise algorithm" » "_ optimized algorithm", "_ optimized algorithms", "_ optimizer algorithms", "_ optimize algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("jose optimisation algorithm") or ((("_ optimise algorithm") or ("_ optimizedddr algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("jose optimisation algorithm") OR ((("_ optimise algorithm") OR ("_ optimizedddr algorithms")))).
• Removing quotes may allow a broader search: (( jose optimisation algorithm ) or ((( _ optimise algorithm ) or ( _ optimizedddr algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("jose optimisation algorithm") or ((("_ optimise algorithm") or ("_ optimizedddr algorithms"))))*.
